British Pound plunges amid suspected Yen intervention

• GBP/JPY falls around 2.4%, collapsing from near 218.00 to the 213.20 area.
• The Bank of England keeps interest rates unchanged at 3.75% in a hawkish 6–3 vote.
• A sudden Yen rally fuels speculation that Japanese authorities intervened in the currency market.

The GBP/JPY cross trades sharply lower near 213.20 on Thursday, losing around 2.4% as a sudden surge in the Japanese Yen (JPY) overwhelms the British Pound’s reaction to the Bank of England’s (BoE) monetary policy announcement.

The BoE maintained its benchmark interest rate at 3.75%, as widely expected. However, the decision was considered a hawkish hold after six policymakers voted to maintain rates and three supported a 25-basis-point increase to 4.00%. Markets had generally expected only two members to vote for a hike.

The BoE acknowledged that United Kingdom (UK) inflation declined to 2.6% in June but warned that higher energy prices could push inflation back up later this year. Policymakers also indicated that the risks surrounding the inflation outlook remain tilted to the upside, particularly if elevated energy costs generate stronger wage and price pressures.

Despite the hawkish vote split, Sterling failed to retain support against the Yen. The Japanese currency strengthened abruptly across the market, sending USD/JPY below 160.00 and causing substantial declines in EUR/JPY and GBP/JPY. The speed and scale of the movement prompted speculation that Japan’s Ministry of Finance had instructed the Bank of Japan to purchase Yen, although the operation has not yet been officially confirmed.

Japanese authorities had repeatedly warned that they were prepared to take decisive action following the Yen’s decline toward 40-year lows near 164.00 against the US Dollar. Thursday’s movement therefore appears consistent with a possible intervention aimed at reducing excessive and one-sided currency volatility.

Short-term technical analysis:

On the 4-hour chart, GBP/JPY trades at 213.06, extending a bearish near-term bias after slipping well below its recent consolidation range. The pair now trades under both the 20-period Simple Moving Average (SMA) at 217.61 and the 100-period SMA at 217.87, which together suggest a deteriorating trend structure and keep any rebound attempts capped for now. The Relative Strength Index (RSI) has plunged to oversold territory near 15, hinting at stretched downside conditions, but the presence of multiple overhead levels keeps recovery prospects fragile while price holds at current depressed levels.

On the topside, immediate resistance emerges at the recent horizontal barrier at 213.96, ahead of 215.50 and 217.40, with the 20-period SMA at 217.61 and the 100-period SMA at 217.87 reinforcing a dense supply zone higher up. On the downside, initial underlying demand is seen at the horizontal support at 214.70 where it started the month, where any pause in selling could trigger a corrective bounce; a sustained break beneath this floor would open the way to further losses in the coming sessions despite the oversold RSI backdrop.
